Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on DSM 115424 when used as a technological additive to improve ensiling of all fresh plant material for all animal species at a proposed minimum concentration of 1 × 10 colony forming units (CFU)/kg fresh plant material. The bacterial species is considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment. The identity of the strain was established, and no acquired antimicrobial resistance genes of concern were detected. Therefore, the FEEDAP Panel concluded that the use of the strain as a silage additive is considered safe for all animal species, for consumers of products from animals fed with the treated silage and for the environment. Regarding user safety, inhalation and dermal exposure are considered a risk. One preparation of the additive containing whey powder as a carrier was shown not to be irritant to skin or eyes. However, the Panel cannot assess the irritation potential of other possible preparations. The FEEDAP Panel concluded that DSM 115424 has the potential to improve the production of silage prepared from all fresh plant materials at a minimum concentration of 1 × 10 CFU/kg fresh material.
应欧盟委员会的要求，欧洲食品安全局（EFSA）被要求就DSM 115424用作技术添加剂时的安全性发表科学意见，该添加剂拟以1×10菌落形成单位（CFU）/千克新鲜植物材料的最低浓度用于改善所有动物物种的所有新鲜植物材料的青贮。欧洲食品安全局认为该细菌物种适用于安全性评估的合格假定安全性方法。已确定该菌株的身份，且未检测到任何令人担忧的获得性抗菌抗性基因。因此，饲料添加剂和产品授权小组得出结论，认为将该菌株用作青贮添加剂对所有动物物种、食用经处理青贮饲料动物的产品的消费者以及环境均安全。关于使用者安全，吸入和皮肤接触被视为有风险。一种以乳清粉为载体的添加剂制剂对皮肤或眼睛无刺激性。然而，该小组无法评估其他可能制剂的刺激潜力。饲料添加剂和产品授权小组得出结论，DSM 115424有潜力以1×10 CFU/千克新鲜材料的最低浓度改善由所有新鲜植物材料制备的青贮饲料的产量。
